在头文件 <string.h> 中定义
|
||
char *strncpy( char *dest, const char *src, size_t count ); |
||
count
字符的字节串的副本指出,src
(包括终止空字符)的字符数组指出,dest
. 原文:
Copies at most
count
characters of the byte string pointed to by src
(including the terminating null character) to character array pointed to by dest
. count
达到之前的整个字符串src
被复制,产生的字符数组是不是空终止原文:
If
count
is reached before the entire string src
was copied, the resulting character array is not null-terminated.之后,如果从
src
终止空字符复制,count
没有达到,额外的空字符,直到总的dest
字符写入count
已经写.原文:
If, after copying the terminating null character from
src
, count
is not reached, additional null characters are written to dest
until the total of count
characters have been written.如果字符串重叠,该行为是未定义.
原文:
If the strings overlap, the behavior is undefined.
